The front of the bed is provided with a workpiece turning mechanism. The workpiece turning mechanism is composed of a workpiece fixing table and a workpiece shaft arranged on it. The workpiece to be ground is clamped on the workpiece shaft. The inner hole of the workpiece and the workpiece The inner hole grinding rotary mechanism corresponds, and the outer circle of the workpiece corresponds to the outer cylindrical grinding rotary mechanism.

In the vertical compound grinding machine, the inner hole grinding rotary mechanism includes a Y-axis carriage fitted on the Z-axis carriage, an inner hole grinder mated and connected to the Y-axis carriage. The head and the inner hole grinding wheel also include a Y-axis feed motor fixedly connected to the Z-axis carriage, and the Y-axis feed motor drives the Z-axis carriage to move up and down through a screw rod.

In the above described vertical compound grinding machine, the cylindrical grinding rotary mechanism includes an X-axis carriage fitted on the Z-axis carriage, and a cylindrical grinding wheel matched and connected to the X-axis carriage. The motor spindle and the cylindrical grinding wheel also include an X-axis feed motor fixedly connected to the Z-axis carriage, and the X-axis feed motor drives the X-axis carriage to move up and down through a screw.

The utility model can realize the grinding of the inner hole and the outer circle by one clamping of the workpiece, so the machining precision is high, the operation is simple and the production efficiency is high, and it is especially suitable for batch processing.
